SEWING uncrrmnnr'mcnmnnr Application filed January 24, 1931. Serial No.51s1,066;

This invention relates to a sewing machine attachment and has for its primary object to provide, in a manner as hereinafter set forth, an attachment of this character. embodying a pnovel construction and arrangement of parts for turning inside out or reversing belts for dresses, coats and other apparel 1I1'Wl11Cl1 a French seam has been sewed by the machine as the French seam is sewed in the belt, thus 2 eliminating the necessity of performing this operation manually after the French seam has been completed.

Other objects of the invention are to pro or belt reversing rod.

-, Figure 12 is a detail view in elevation vide a sewing machine attachment of the character described which will be simple in construction, durable, efiicient and reliable in operation, which may be expeditiously mounted for use on a conventional sewing machine without materially altering said machine structurally and which may be manufactured at low cost. 7

All of the foregoing and still further objects and advantages of the invention may become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein Figure 1 is a view in top plan showing an attachment in accordance with this invention mounted in position on a sewing machine.

Figure 15 is a detail view in side elevation of the rod coupling member illustrated in. Figure 14. 1 1 V Referring to the drawings indetail, it will be seen that the reference numeral 1 designates a" conventional sewing machine which is mountedinthe usual manner on a table 2 Mounted on the table 2 forwardly of the sewingmachine 1 is a flat metallic plate 3 having openings 4, therein for the passage of securing elements for rigidly mounting the plate in position on the table. The metallic plate3 is providedwith an upwardly offset portion 5 which terminates in a rolled free end portion-constituting a sleeve 6 having a notch 7 in one end thereof for a purpose which will he presently set forth.

Anelongated tube 8 which is open 'at both ends is mounted for longitudinal sliding movement inthe sleeve 6 and is provided with a laterally projecting handle 9 adjacent its rear end for manually'shifting the tube. The stem or shank of the handle 9 is engageable in the notch 7.0f' the sleeve 6 to limit the slidingmovement of the tube 8 in a forward direction and also in a manner to limit the ing therefor in the sleeve 6 for engagement. with the tube 8. The outer end of the. keeper.

12 is provided with a head 13 to facilitate obtaining a grip on'the keeper. Adjacent the standard 10 the opposite sides of the tubular casing 11 are provided with the longitudinally extending slots 14 inwhich the projecting end portions of a pin 15 which extends transversely through the keeper 12 are operable. A coil spring 16 encircles the tubularv casing 11 and has one end engaged with the standard 10 and its other end engaged with the projecting endportions of the pin-15 in a manner to yieldingly urge the keeper 12 into engagement with the tube 8 in a manner to frictionally retain said tube in adjusted position in the sleeve 6.

- Longitudinally aligned upstanding brack ets 17 are rigidly mounted on the table 2 and are provided with openings 18 which are disposed in longitudinal alignment with the bore of the tube 8. An elongatedbelt reversing r0d19 is mounted for sliding'movement in the brackets 17 through the openings 18therein and said rod 19 is, of course,- disposed in longitudinal alignment with the tube 8. A bracket 20 which is identicalin construction to the brackets 17 is mounted diagonally on the table 2 adjacent the plate 3, as best seen in Figure 1 of the drawings and slidably supports one end portion of an operating rod 21 having a handle grip 22 on said one end- The other end of the operating rod 21 is pivotally and operatively connected to a swingable coupling rod 23 by a coupling member which is designated generally by the reference numeral 24. The swingable rod 23 is pivotally mounted for movement in a horizontal-plane on an upstandin bracket 25 having a foot portion 26 (see igures 9'and 10) which is rigidly anchored to the table 2 andfurther having a horizontally disposed upper end portion 27 to which the rod 23 is connected as at 28. The coupling or rod 23 is operatively connected to the reversing rod 19 as at 29,- the coupling member used at 29 being identical in construction to the member 24. As best seen in Figures 14 and 15 of the drawings, the coupling member 24 comprises apair of pivotally connected blocks 30 having openings 31 extending therethrough for the passage of the various rods.- Set screws 32 are threaded into the free ends of the blocks 30 for engagement with certain of the rods for secur;

ing the coupling members thereto. The coupling members 24 and 29 are rigidly secured to the rods 21 and 19, respectively, but'are slidably connected .to the swingable rod 23' this invention the material is first folded as in Figure 6 of the drawings and the tube 8 is shifted to the retracted position illustrated in Figure 5 of the drawings. This is to permit the end portions of the folded belt 33 to be sewed transversely as at 34 on the machine 1. The tube8 is then moved forwardly to the position illustrated in Figure 8 of the drawings and the belt 33 is mounted thereon. In this position the free longitudinal edges of the folds ofthe belt are dis posed beneaththe needle, bar of the machine 1 and said machine is then actuated and the belt 33 is fed beneath the needle bar and guid-' ed; with one hand by the operator. WVith the other hand the operator grasps the handle 22v and pulls the rod 21 toward himself or substantially toward himself. This operation of the rod 21 moves the reversing rod 19 .forwardly through the medium of the swingable rod 23.and the coupling elements 24 and 29. The rod 19 engages the sewed end of the belt and forces the'belt, as said belt is sewed through thetube 8, it is understood, of course, that during this operation the forward end of the tube 8 is projected beyond the needle bar of the machine 1. This movement of the reversing rod 19 is continued until the belt is projected thereby from the rear end of the tube 8 after which the rod 19 is returned to its inoperative position as illustrated in Figure lot the drawings and the operator grasps the end portion of the belt which has been thus projected from the rear end of the tube Sand continues to pull said belt through the tube 8.

It is believed that the many advantages of a sewing machine attachment in accordance with this. invention will be readily under stood, and although the preferred embodiment of the invention is as illustrated and described, it is 'to be understood that changes in the details of construction may be had which will fall within the scope of the .invention as claimed.

WVhat is claimed is 1. A belt inverting attachment for sewing machines comprising a horizontally disposed plate having a vertically ofi'set portion, a sleeve on the offset portion, an elongated tube mounted for sliding adjustment in'the sleeve and adapted for insertion in the belt in a manner to support said belt during the sewing of a means for manually actuating the slidable rod.

2. A belt inverting attachment for sewing machines comprising a horizontally disposed plate having a vertically ofi'set portion, a sleeve 011 the offset portion, an elongated tube mounted for sliding adjustment in the sleeve and adapted for insertion in the belt in a manner to support said belt during the sewing of the longitudinal marginal portion thereof, a slidable rod engageable with the belt for inserting and driving said belt through the tube as the sewing operation progresses, means for manually actuating the slidable rod, and a slidable, spring actuated keeper mounted on the plate and engageable with the tube in a manner to releasably secure said tube in adjusted position in the sleeve. 3. A belt inverting attachment for sewing machines comprising a horizontally disposed plate having a vertically ofiset portion, a sleeve on the offset portion, an elongated tube mounted for sliding adjustment in the sleeve and adapted for inserting in the belt in a manner to support said belt during the sewing of the longitudinal marginal portion thereof, a slidable rod engageable with the belt for inserting and driving said belt through the tube as the sewing operation progresses, means for manually actuating the slidable rod, and a slidable, spring actuated keeper mounted on the plate and engageable with the tube in a manner to releasably se- 85 cure said tube in adjusted position in the sleeve, said means for actuating the slidable rod comprising a pivoted rod operativel-y connected to the slidable rod, and another rod mounted for sliding movement and having a gripping handle on one end and its other end operatively connected to the pivoted rod.
